SPEGIFIOATIONforming part of Letters mete No. 509,196, dated November21, 1893.

Application filed June 19,1893.

To all whom it may concern.-

Be it known that I, GEORGE A. CLAPP, of

' Quincy, county of Norfolk, State of Massachusetts, have inventedanImprovement in Opera- Chairs, of which the following description, inconnection with the accompanying drawings,is a specificatiomlike lettersand figures on the drawings representing like parts.

This invention has for its object to provide a novel opera chair whichmay be readily moved back by the occupant of the chair without risingfrom it, to enable a person to pass.

In theaters and other public places where an audience is seated for aperformance it is very desirable to use as little space as possible foreach chair, and as such chairs are now made, a person occupying a chairis obliged to rise and tip up the seat of the chair in order to letanother person pass to a seat in the same row. I have aimed to sosupport the chair seat that it may tip upon its frame, and also bepushed back away from a row of chairs in front, to thus affordagangwayof sufficient size to let a person pass without seriously incommodingthe occupant of the seat. In accordance with my invention the seat-frameis mounted on rockers, as will be described.

Figure 1, in side elevation'shows a chair embodying my invention, thechair being in its normal forward position, with seat down; Fig. 2 alike view with the seat pushed back; Fig. 3 a rear view of the chair;and Fig. 4 shows one of the legs detached.

The base of the chair consists of two feet A, A, having ears a, a,between which are entered the lower ends of the legs or supports B, thelower end of the leg mounted on a pivot I) being beveled or shaped asshown in Fig. 4, thus leaving surfaces 1), b to act as stops and limitthe extent of the rocking movement of the legs. The upper ends of thelegs, beveled to form stops b 1) for the seat 0, are embraced by theears 0, c, to which is connected Serial No. 478,089. (No model.)

the back 0 the back being shown as provided with suitable arms 0 Theears 0, c, and the upper parts of the legs are connected by a.

pivot pin 3, the location of the pivotal points I) and 3 being such asto cause the weight of the parts to put the chair normally in theposition Fig. 1. The seat itself is pivoted at 4 on or with relation toears 0, 0, so that the seat may turn about said pivot 4, as usual.Suppose the seat, Fig. 1, to be in its usual position in a row, andoccupied, and that another person desires to pass the one occupying theseat. To provide for this, the 08011, pant of the chair has only to pushhimself back while in the seat, as in the position Fig. 2, the stop bthen resting against the foot.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. The herein described opera chair composed of a back having ears; apivoted seat; and rocking legs, one pivotedito each ear, said legshaving stops at each side of their pivotal connections, and pivotalsupports at their lower ends, substantially as shown and described.

2. The back having ears, the seat pivoted thereon, the legs having'stopsat their upper ends, pivots jointing the ears of the back with the saidlegs,'and feet having ears to which the lower ends of the legs arejointed by piv-' GEO. A. OLAPP.
